A veteran Food and Drug Administration (news - web sites) safety
officer said yesterday at a Senate hearing on the abrupt recall of
the arthritis drug Vioxx that five other widely used drugs should
either be withdrawn or more sharply restricted because they have
dangerous side effects.

Describing the agency he works for as incapable of stopping dangerous
drugs from entering and staying on the market, David J. Graham,
associate director of the Office of Drug Safety, told the senators
that the FDA (news - web sites)'s role in reviewing and approving new
drugs sometimes conflicts with its duty to address safety issues.


Asked by Sen. Jeff Bingaman (news, bio, voting record) (D-N.M.) to
identify the five drugs, Graham hesitated and then named them to the
startled listeners: the popular cholesterol-lowering drug Crestor,
the weight-loss drug Meridia, the painkiller Bextra, the acne
medication Accutane and the asthma medication Serevent.


Each poses different issues, Graham said in response to senators'
questions, but all require more aggressive FDA action.


AstraZeneca's Crestor, he said, poses risks of kidney failure and a
rare muscle disease; Abbott Laboratories' Meridia is of little use
and has cardiovascular side effects; Roche's Accutane can cause birth
defects if used by pregnant women; Pfizer's Bextra carries
cardiovascular risks similar to those linked to Vioxx; and
GlaxoSmithKline's Serevent increases the risk of dying of asthma. The
makers of all five drugs later defended their products vigorously.


A 20-year veteran of the FDA, Graham has played a significant role in
the withdrawal of nine drugs over the past decade, and his highly
unusual attack on his own agency astonished many in the hearing room.
He called the FDA's handling of Merck & Co.'s Vioxx -- which he said
should have been pulled from the market years ago -- the most
distressing episode of all and a "profound regulatory failure."


"I would argue that the FDA as currently configured is incapable of
protecting America against another Vioxx," Graham said in his
scathing assessment. "The scientific standards [the FDA] applies to
drug safety guarantee that unsafe and deadly drugs will remain on the
U.S. market."


Citing estimates he said were based on the results of Merck's own
clinical trials, Graham said that between 88,000 and 139,000
Americans probably have had heart attacks or strokes as a result of
taking Vioxx, and that 30 to 40 percent probably died.


Graham's sentiments were endorsed at the hearing by two other drug
safety experts, but they were disputed by a ranking FDA official as
"not the FDA that I know."


Sandra L. Kweder, deputy director of the Office of New Drugs, said
that the agency is dedicated to protecting consumers and that drug
safety is at the heart of its activities. She acknowledged, however,
that "clearly, there's concern by the public and this committee that
the system isn't working as well as it should, and we need to address
that."


Asked about the five drugs that Graham identified as needing
immediate action, Kweder said, "I don't have reason to believe that
set of five drugs gives more reason for concern than any other set."


Graham's revelations and criticisms were the centerpiece of the
hearing called by Sen. Charles E. Grassley (news, bio, voting record)
(R-Iowa), chairman of the Senate Finance Committee and an
increasingly sharp critic of the FDA. After Graham's comments,
Grassley pointedly warned agency officials against disciplining
Graham in any way.


Merck chief executive Raymond V. Gilmartin came to the defense of the
FDA and his company's actions in dealing with the issues around
Vioxx, a heavily advertised and hugely profitable drug until it was
abruptly recalled in September. He said the company had no scientific
reason to withdraw the drug until it heard clear negative results
reported by the safety monitoring committee of an ongoing clinical
trial. At the time, Gilmartin said, his wife was taking the drug
regularly.


"Throughout Merck's history, it has been our rigorous adherence to
scientific investigation, openness and integrity that has enabled us
to bring new medicines to people who need them," Gilmartin said. "I
am proud that we followed that same rigorous scientific process at
every step of the way with Vioxx."


The drug, which was introduced in 1999, is among a class of
painkillers known COX-2 inhibitors that are widely used by people
with arthritis. It was withdrawn after researchers stopped a clinical
trial because patients taking Vioxx were experiencing twice as many
heart attacks and strokes as patients taking a placebo, but witnesses
testified there had been suggestions of possible cardiovascular risks
dating to the mid-1990s.


Graham, Stanford University COX-2 expert Gurkirpal Singh and
University of Washington drug safety expert Bruce M. Psaty all said
Merck and the FDA should have been more attentive to the "signals" of
trouble in Vioxx studies as far back as the 1990s.


This has been a difficult week for the FDA, which was sharply
criticized Wednesday in a congressional hearing into the shortage of
flu vaccine. The agency has been without a permanent commissioner for
more than two of the past four years, and three important divisions
-- the Center for Drug Evaluation and Research, the Office of New
Drugs and the Office of Drug Safety -- are all being headed by acting
or deputy directors.

   



Officials of the companies whose drugs were cited by Graham said they
were surprised by his testimony. Carolyn Glynn, a spokeswoman for
Roche, said the firm has long recognized that Accutane -- used to
treat serious acne that does not respond to other medications --
requires special handling because of its known connection to birth
defects. Female users must first have a pregnancy test and may get
only one month's supply at a time.

AstraZeneca said in a statement that "to date, the FDA has not given
the company any indication of a major concern regarding Crestor, and
the comments today are inconsistent with past public statements from
the FDA." More than 12 million prescriptions for the drug have been
written worldwide.

Abbott Laboratories issued a statement defending Meridia, which 15
million patients worldwide have used since 1997. "Obesity remains one
of the leading health epidemics in the U.S., and Meridia is one of
the few effective drugs that are currently available," it said.

GlaxoSmithKline stood by its asthma drug Serevent, which Graham said
can make the condition worse and even be deadly. Serevent, used by 23
million patients worldwide since 1990, "is safe and effective when
used appropriately," the company said. A black box warning was placed
on the drug's label in August 2003.

Pfizer spokeswoman Susan Bro said its COX-2 inhibitor, Bextra, "has
been found safe and effective when used as indicated." She noted that
the company has "committed to conducting further studies to confirm
the longer-term cardiovascular safety profile." More than 7 million
Americans have taken it.
